Matter &Mixture. Gas: A gas can be poured and be compressed. It changes shape all the time. It shapes to fit the container completely, it can diffuse and it diffuses quickly.
Liquid: any combination or blend of different elements, kinds, qualities, etc.: a mixture of good and bad traits.(dictionary meaning). Liquid is not a mixed shape, therefore it will shape to fit the container it is placed in. A liquid can be poured.Water is made up of molecule. Liquid has a fixed volume, a liquid can diffuse and it diffuses slowly. You cannot compress water
Solid: A solid (i.e ice) is a fixed shape and it will not change shape unless it is broken or water is put on it (depending if the solid is effected by H20). A solid cannot be poured. A solid does not diffuse.
What is sublimation? Sublimation is when a solid is turned straight into a gas (adding energy). Supposing you increased the pressure of the air above the boiling liquid. What would happen to the boiling point of the water? It makes a fog around the container, then it turns back into a liquid.
Imagine you are trying to boil water for a cup of tea up a mountain. Why would the cup of tea be fairly horrible? Because you are on a mountain (very cool weather), the water would be very hard to boil. A cold cup of tea tastes fairy horrible.
Does water contract or expand on changing from a liquid to a solid? When a liquid (water) changes to a solid (ice) it expands.
The states of matter.
Why do gases exert pressure on the walls of their container? Because the particles hit the walls of their container. What happens to particles when they are heated up? They stay the same size. When particles are cooled down they... Vibrate less and move closer together. Which matters can flow? Liquids and gases. Solids, liquids and gases expand when you heat them up, what happens to them when they are cooled down? They contract. What happens to the pressure in a metal spray can when it is heated up? In increases.
Colloids.
Smoke. ·Smoke is an example of a colloid, formed when a solid (carbon) is spread throughout a gas. ·Smoke is a colloidal dispersion. ·An example of smoke is factory smoke ·Many factories produce soot particles referred to as black carbon, which plays a major role in global warming
